Abstract
Official abstract text for this publication.
An electric power converter that can easily be assembled is provided. An electric power converter includes a semiconductor stacking unit, a frame and a spring unit. The semiconductor stacking unit has a configuration in which the semiconductor modules and coolers are stacked. The spring unit is inserted between one end of the semiconductor stacking unit in a stacking direction, and a support provided on the frame, and fixes the semiconductor stacking unit while applying pressure thereto. The spring unit is provided with a first plate, a second plate, and a coil spring sandwiched between the first and second plates. A recess is provided in the first plate so as to have a gap between the first plate and the end surface of the semiconductor stacking unit. A penetrating passage through which the entire spring unit passes along a bottom of the recess is provided in the spring unit.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electric power converter comprising: a semiconductor stacking unit configured to alternately stack a flat type semiconductor module and a flat type cooler, the semiconductor module containing a semiconductor element; a frame for placing the semiconductor stacking unit; and a spring unit that applies pressure to the semiconductor unit, the spring unit being inserted between an end surface of the semiconductor unit in a stacking direction and a wa…
